Expected system data flows and interconnections.

An accurate diagram of your current network and firewall topologies.

Access to firewall logs to be analyzed against the firewall rule base so you can understand the rules that are really being used.

The critical information you need to gather to plan the audit work includes:

Your firewall audit probably wonвЂ™t succeed if you donвЂ™t have visibility into your network, which includes hardware, software, policies, as well as risks.

#ISO 27002 CHECKLIST HOW TO#

And since ISO 27001 doesnвЂ™t specify how to configure the firewall, itвЂ™s important that you have the basic knowledge to configure firewalls and reduce the risks that youвЂ™ve identified to your network. YouвЂ™re not going to pass an ISO audit just because you picked any specific firewall.Д¬onsequently, the following checklist of best practices for firewall audits offers basic information about the configuration of a firewall. This is critical when you undergo an ISO audit. Rather, you must document the purpose of the control, how it will be deployed, and what benefits it will provide toward reducing risk. And the brand of firewall you choose isnвЂ™t relevant to ISO compliance.

The ISO 27001 standard doesnвЂ™t have a control that explicitly indicates that you need to install a firewall. ItвЂ™s critical that you know how to implement the controls related to firewalls because they protect your company from threats related to connections and networks and help you reduce risks. So you have to perform a risk assessment to find out what kind of protection you need and then set your own rules for mitigating those risks.

Since ISO 27001 doesnвЂ™t set the technical details, it requires the cybersecurity controls of ISO 27002 to minimize the risks pertaining to the loss of confidentiality, integrity, and availability. As such, you should automate the process to audit your firewalls because itвЂ™s important to continually audit for compliance, not just at a particular point in time.Д«asically, a firewall is a cybersecurity tool that manages connections between different internal or external networks that can accept or reject connections, or filter them under specific parameters.

And that takes a toll on your information security staff.ДЄs networks become more complex, so does auditing. ThatвЂ™s because when firewall administrators manually conduct audits, they must rely on their own experiences and expertise, which usually varies greatly among organizations, to determine if a particular firewall rule should or shouldnвЂ™t be included in the configuration file.ДЄdditionally, because the documentation of the current rules and the evolution of their changes isnвЂ™t typically up to date, it takes time and resources to manually find, organize, and review all of the firewall rules to determine how compliant you are.

However, these audits can also play a critical role in reducing risk and actually improve firewall performance by optimizing the firewall rule base.Д«ecause of todayвЂ™s multi-vendor network environments, which usually include tens or hundreds of firewalls running thousands of firewall rules, itвЂ™s practically impossible to conduct a manual cybersecurity audit. These audits ensure that your firewall configurations and rules adhere to the requirements of external regulations and your internal cybersecurity policy. Because of additional regulations and standards pertaining to information security, including Payment Card Industry Data Security Standard (PCI-DSS), the General Data Protection Regulation (GDPR), Sarbanes-Oxley (SOX), the Health Insurance Portability and Accountability Act (HIPAA), California Consumer Privacy Act (CCPA) and ISO 27001, organizations are putting more emphasis on compliance as well as the auditing of their cybersecurity policies and cybersecurity controls.Д®ven if your company doesnвЂ™t have to comply with industry or government regulations and cybersecurity standards, it still makes sense to conduct comprehensive audits of your firewalls on a regular basis.
